To ct'ZZ whom it may @012 com:

Be it known that we, WILBUR W'. MARSH and CHARLES H. HAOKETT, citizens of the United States of America, and residents of the city of WVaterloo, Blackhawk county, and State of Iowa, have invented certain new and useful Improvements in Centrifugal Liquid- Separators, of which the following is a specification.

Our invention relates to improvements in centrifugal liquid-separators and the objects of our improvements are, first, to provide an improved liner having a series of plates superimposed one above another and inclined toward its center to retard the progress of the liquid in its descent from the top to the bottom of the separator-bowl; second, abowl so devised as to permit of the withdrawal of the lighter constituent of its contents from the top and the heavier constituent from the bottom; third, a bowl containing a compartment so arranged as to separate any solid particles or impurities from the liquid before the introduction of said liquid into the compartment of the bowl which contains the liner; fourth, a connecting-rod having at its top portion a central cavity for the reception of a liquid, said cavity communicating with the upper compartment of the bowl through openings on the sides thereof; fifth, a bowl separated into compartments and provided with an annular recess in the bottom of the interior periphery of its sides to permit the passage of the liquid beneath the bottom of the liner; sixth, a liner arranged to closely engage the interior periphery of the bowl; seventh, a liner so arranged as to permit of the withdrawal of the lighter constituent of the liquid through the top of the bowl; eighth, an improved packing for upper compartment of bowl to prevent escape of solid particles from the liquid by centrifugal force, and, ninth, an improved holder for retaining the upper pan of separator in proper position surrounding but not touching the top of the bowl. We attain these objects by the means illustrated in the accompanying drawings, in which Figure l is a side elevation of the bowl with the top and bottom pans in operative position, the top pan supported by our pan-holder and theinterior construction of the pans indicated by dotted lines; Fig. 2, a vertical section of the bowl, showing the liner in position within it; Fig. 3, a vertical section of the separable top of the bowl; Fig. 4, a plan view of the under side of the separable upper portion of the bowl; Fig. 5, ahorizontal section of the liner on the line {D a; of Fig. 2; Fig. 6, a plan View of the under side of the bottom plate of the liner; Fig. 7, a'plan view of the upper surface of the bottom of the interior of the bowl; Fig. 8, a side elevation of the connecting-rod; Fig. 9, a vertical section of the connecting-rod; Fig. 10, a horizontal section of the hollow upper portion of connectingrod on the line 'y y of Fig. 9; Fig. 11, a top plan view of thepan-holder, showing the top pan of separator in position within it. Fig. 12 is a front elevation of one of the spraying tubes of liner, and Fig. 13 is a perspective View of the liner.

Similar numbers refer to similar parts throughout the several views.

The cylindrical bowl 19 is provided with the usual spindle 43. About the bottom of its interior periphery is an annular recess 13. A threaded hole 25 is placed at the center of the upper surface of the bottom of. the inte rior of the bowl for the reception of the screw 2i on the connecting-rod 16. About this are disposed the ducts la'for the purpose of withdrawing the heavier constituent of the liquid.

23 is a hole in the bowl for the reception of a stud 15 on the bottom of the liner, which latter serves to retain the linerin place within the bowl.

The ducts 1i deliver the heavier constituent of the liquid into the bottom pan 39 of the separator. This bottom pan is provided with central openings, through which the spindle of the separator passes. The liquid is ejected from the ducts let into the pan 39,

between its cover 38 and its inclined bottom 40, whence it fiows to any convenient receptacle through the spout 41.

18 is a cover of a circular shape and arched in section, having its top part provided with close contact with the upper surface of the top plate of the liner. The circumferential edge of the cover 18 is beveled to permit of the introduction of the packing-ring 46 between it and the liner. The packing-ring 46, which may be constructed of rubberor any other suitable material, is placed within the recess formed between the beveled edges of the cover and the top plate of liner and the interior periphery of the bowl. Its function is to prevent the escape of matter collected within the interior of the upper compartment. The interior partitions 3 and 4 carry the liquid with .the revolving bowl, placing it under pressure, and results in the solid particles of impurities therein being thrown to the circumference of the compartment. The connecting-rod 16 serves to clamp and compress together the cover and liner of the separator by being passed through openings in both and having its threaded end 24 screwed into the hole 25 in the bottom of the bowl 19. This method of clamping produces a compression upon the packing free from twisting stress such as is produced by covers which are screwed directly to bowl. The upper end of the connecting-rod 16 has a cylindrical cavity 26, open at the top and closed at the bottom. Onthe opposite sides of the enlarged portion of the rod 16 are placed the openings 7 and 8, eachof said openings being provided with blades, such as 5 and 6, extending inwardly.

The function of the blades 5 and G is to divert the liquid which is conveyed into the cavity 26 through the openings '7 and 8 into the'upper compartment, between the cover 18 and the top plate 2 of the liner. The openings'7 and 8 are so placed within the sides of theenlargement of the connecting-rod 16 as to open wholly within the interior of the upper compartment.

The liner is composed of the circular top andbottom disks 2 and 11, connected together by means of the radial wings 10. The disks 2 and 11 are provided with holes for the reception of the connecting-rod 1G. The top disk 2 is beveled at its outer circumferentiz-tl edge for the reception of the packing-ring 46. Tlie'bottom disk 11 has transverse supportingpieces 12 to keep it a su'fficient distance from the bottom of the bowl, and also has a stud 15 for the purpose of retaining it in position in the'bowl. The tubes 48 are attached to the topdisk of liner, opening through it to-communicate between the upper and lower compartments of the bowl. The lower ends of the tubes 48 are incurved beyond the inner side-of duct 1. This curving in of the tubes 48 renders the closing of the tubes at the bot tom unnecessary, because the line of the outlet to the lighter particles is the point where they cease to flow toward the center. forations 49 are placed within the walls of the tubes 48 along that side of the tubes which follow the revolution thereof, and the liquid in descending within the tubes is sprayed v through the spout 37.

Per-

per end of saidduct 1 passes through the top disk 2 of the liner and the upper part 17 of the cover 18, and the lighter constituent of the liquid which is forced through it is received within the interior of the top pan 29, between its cover 28 and its inclined bottom 30, whence it passes off to any convenient receptacle The liner is provided with a series of partition-plates inclined toward the center, superimposed one above another and-attached to the radial wings 10.

The outer edges of these partition-plates 20 are so curved as to closely engage the inner periphery of the bowl and are furnished with apertures 47 to allow the liquid to descend through them. The inner edges of the plates 20 are placed at a sufficient distance from the connecting-rod 16 to permit of the free ascent of the lighter constituent of the liquid.

The upright support 35 has its lower end 36 turned eccentrically in order to allow any desired adjustment of the pan 29 about the bowl 19. The pan-holder may be set at any desired height by means of the thumbscrew 3st. This pan-holder is formed of the separable members 32 and 42, whose'inside' edges are formed of a shape suitable to en'- gage and hold the lower part of the pan 29 when placed within them. The pan 29 engages the inner periphery of the members 32 and 42, but does not touch the outer surface of the bowl 19. After long, use a bowl'becomes unbalanced. It may then by impact violently shatter exteriorboxing, endangering the operator. The use of our pan-holder with an nnboxed bowl obviates this danger. The top pan 29 has a cup .27, in whose bottom is placed a small circular orifice, through which liquids may pass downward into the cavity 26 of the connecting-rod 16. A crescent-shaped opening 44: is placed in the top of the cover 28 in order to permit the operator to look within the pan when adjusting the pan over the top of the separator-bowl.

The operation of ourimproved separatoris thus described: lVhen the liquid is poured into the cup 27, it drains thence through the orifice 45 into the cavity 26. The centrifugal force imparted to the liquid by its contact with the blades 5 and 6 causes it to move through the openings 7 and 8 into the spaces of the upper compartment of the separator whichare formed by the partitions 3 and 4 of the cover 18. The partitions 3 and et' carry the liquid with the rapidly-revolving bowl, causing the solid particles or impurities contained in-the liquid to be separated therefrom and accumulated at the outer limits of the spaces, where they collect and are prevented from passing into the bowl by the packingring 46. The milk or other liquid to be sep arated being thus purified descends into the bowl through the perforated tubes 48. As it descendsinto the bowl and is sprayed through the perforations 49 the liquid impinges upon the inclined plates 20 and the lighter constituent of the liquid separates from the heavier particles, the lighter particles seeking the center of the bowl, while the heavier move toward the inner periphery thereof. As the lighter particles are deflected back from the inner periphery of the bowl they flow down the under surfaces of the partitionplates 20 until they have passed below the inner edge thereof, when they join the current moving toward duct 1. The heavier parti* cles descend to bottom of bowl through the openings 47, whence they pass beneath the bottom plate 12 of liner through the annular recess 13 into the ducts 1-1 and thence out into the bottom pan 39.
